Common Equinix Metal Issues and Solutions

1. Server Provisioning Failures

Instances may fail to provision correctly due to resource constraints, region-specific availability issues, or incorrect configurations.

Root Causes:

Insufficient available capacity in the selected region.
Incorrect server plan selection or incompatible hardware settings.
Network boot failure or misconfigured PXE boot settings.

Solution:

Verify server availability before deployment:

metal project capacity --metro sv

Ensure that your provisioning request aligns with available hardware:

metal device create --plan c3.small.x86 --metro sv

For PXE boot failures, verify BIOS settings and ensure DHCP is correctly configured.

2. Network Connectivity Issues

Network connectivity problems can lead to inaccessible instances, failed SSH connections, and unresponsive applications.

Root Causes:

Incorrect VLAN or subnet assignments.
Firewall rules blocking inbound or outbound traffic.
Misconfigured BGP settings affecting routing.

Solution:

Check the assigned network configuration:

metal network get

Ensure firewall rules allow SSH and necessary application ports:

iptables -L -n

For BGP-related issues, restart BGP sessions and verify peer configurations:

metal bgp session list

3. Block Storage Not Mounting

Block storage volumes may not mount properly, leading to application failures or data unavailability.

Root Causes:

Incorrect file system format.
Missing mount points or incorrect fstab entries.
Storage device not being recognized after provisioning.

Solution:

List available storage devices:

lsblk

Format and mount the storage volume:

mkfs.ext4 /dev/nvme0n1mount /dev/nvme0n1 /mnt/storage

Ensure persistence across reboots by updating /etc/fstab:

echo "/dev/nvme0n1 /mnt/storage ext4 defaults 0 0" >> /etc/fstab

4. Performance Degradation

Users may experience slow application performance due to CPU throttling, network congestion, or inefficient disk I/O.

Root Causes:

High CPU or memory usage exceeding allocated resources.
Disk I/O bottlenecks affecting read/write operations.
Network congestion due to overutilization of available bandwidth.

Solution:

Monitor system performance:

htop

Check disk I/O statistics:

iostat -x 5

Optimize network performance by configuring QoS settings:

tc qdisc add dev eth0 root fq

5. Security Misconfigurations

Improper security configurations can expose servers to potential threats, unauthorized access, and data leaks.

Root Causes:

Weak SSH authentication settings.
Unrestricted public access to critical services.
Misconfigured role-based access controls (RBAC).

Solution:

Disable password authentication and enforce SSH key access:

sed -i "/^PasswordAuthentication/s/yes/no/" /etc/ssh/sshd_configsystemctl restart sshd

Restrict access to critical services using firewall rules:

ufw allow 22/tcpufw enable

Verify user permissions and enforce RBAC policies:

metal project users list

Best Practices for Equinix Metal

Monitor infrastructure health using built-in logging and telemetry tools.
Use multi-region deployments to enhance fault tolerance.
Regularly update server firmware and security patches.
Implement automated backups for critical workloads.

Conclusion

By resolving provisioning failures, network issues, storage challenges, performance degradation, and security misconfigurations, developers can effectively manage and scale their workloads on Equinix Metal. Following best practices ensures a secure, high-performance, and resilient cloud infrastructure.
